I like the general cute and relaxing feel of the game.
Overall the levels are not too difficult but I got myself killed quite a few times getting trapped between the floating death balls because I don't seem to get i-frames when I get hurt. Also the dialog is well presented, so I can enjoy the game and read in my own time.
The controls are responsive and tight, I would like an option to auto attach the characters I like what you did with splitting them for puzzle solving.
Nice work.
